I'd heard that some distros of Linux were having an issue because of the version mismatch between git on the Codeplex server and the git client. Have you tried updating your git client to the latest release to see if that helps?

Just to let you know I'm having the same problem (I'm on Ubuntu 12.04, 32bits Intel)

I also tried upgrading to Git 1.8.0.3 (the Ubuntu package from the Git project) and even tried increasing the post buffer, but always got the same exception. I believe I was able to clone previous versions 0.8.0 and 0.8.1, but not anymore.

I found some suggestions to use something else than HTTPS, but it seems Codeplex doesn't support HTTP:// or GIT:// or GIT+SSH:// protocols.

BTW, I do use GitHub all the time, and there are no problems there. So there are scenario's where a HTTPS based clone is working on my system.

good to know I'm not the only one with this problem. I got around this by running windows 7 on virtualbox and mounting my linux fs in virtualbox. It is odd that git on windows work but not git on linux

The solution I finally got working was setting up a "https tunnel" to codeplex and then use git to connect to the localhost instead and let the tunnel handle the connection. Here you can find some of more details of the steps to followed:

As far as I understand it, it has to do with the size of the repository. If you do some searches you'll find also people using other codeplex repositories having this issue. The earlier versions of TS repository where fine, but once it grew the issue came
into play.

I found a solution while searching. This works for any repo on codeplex or even github. Actually while cloning with https, these require a latest version of git. The git version is not specified hence we need to build git from src(take the latest
version from git's main repo.)
